FAQ

Q1: What does CFU/m mean in viable air sampling?

A: CFU/m stands for Colony Forming Units per cubic meter. It is the standard unit used to report viable microbial concentration in air based on incubated colony counts and the sampled air volume.

Q2: How is a microbial air sampler different from a particle counter?

A: Particle counters measure non-viable particles in real time, while microbial air samplers capture viable organisms onto agar for incubation and counting. Many facilities use both because they support different monitoring goals.

Q3: How do I choose sampling locations and volumes?

A: Follow your SOP and risk assessment. Locations and volumes typically align with critical operations, airflow patterns, and historical trends. Qualification studies often use broader coverage than routine monitoring.

Q4: What causes colony overlap and why does it matter?

A: High microbial load or an unsuitable impactor design can cause colonies to merge on agar, reducing counting reliability. Choosing appropriate sampling volumes and a well-designed head improves count integrity.

Q5: Do microbial air samplers require routine verification?

A: Yes. Verification frequency and methods depend on internal quality procedures and expectations for controlled environments, typically focusing on flow stability and overall performance checks.
